I need to be able to zoom in further in my cmv web map but I can't figure out where this is set. Any suggestions on where to look? I am also wondering if it is possible for opacity in these basemaps.


The zoom levels (aka Levels of Detail or LODs) available for a map ares determined by the first layer that is loaded by the map. Typically this is the basemap you define in the mapOptions section of your viewer/config.js file. The levels are defined within the map service referenced in the basemap. For example, if you used basemap: 'streets', the levels of detail would be 0 through 19 (20 total levels) based on this service: http://services.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer

The other ArcGIS Online basemaps are listed here: http://services.arcgisonline.com/arcgis/rest/services

I don't believe that you can set the opacity of a basemap within the configuration. You might be able to do this using CSS.

  • Thank you for your response. So I guess this means that I cannot zoom in as far as I can in ArcMap? – craigb Mar 24 '15 at 23:38
  • That is correct if you use the ArcGIS Online basemaps. You have more options if you use your own basemaps. – tmcgee Mar 24 '15 at 23:42
